From 5f37fc132a8f41994f37b6712feb2d4fd34c2be0 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 3 Aug 2011 19:57:46 -0400 Subject: further debloat cancellation handlers cleanup push and pop are also no-ops if pthread_exit is not reachable. this can make a big difference for library code which needs to protect itself against cancellation, but which is unlikely to actually be used in programs with threads/cancellation. --- src/thread/pthread_create.c | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'src/thread/pthread_create.c') diff --git a/src/thread/pthread_create.c b/src/thread/pthread_create.c index 0e955911..7be58b99 100644 --- a/src/thread/pthread_create.c +++ b/src/thread/pthread_create.c @@ -39,6 +39,19 @@ void __pthread_do_unwind(struct __ptcb *cb) __syscall(SYS_exit, 0); } +void __pthread_do_register(struct __ptcb *cb) +{ + struct pthread *self = pthread_self(); + cb->__next = self->cancelbuf; + self->cancelbuf = cb; +} + +void __pthread_do_unregister(struct __ptcb *cb) +{ + struct pthread *self = __pthread_self(); + self->cancelbuf = self->cancelbuf->__next; +} + static int start(void *p) { struct pthread *self = p; -- cgit 1.4.1
